B-cell Linker
The B-cell linker protein is encoded by the ''BLNK'' gene and is an adaptor protein also known as SLP-65, BASH, and BCA. BLNK is expressed in B cells and macrophages and plays a large role in B cell receptor signalling, in a fashion analogous to the role its paralogue SLP-76 plays in T cell receptor signalling. As it has no known intrinsic enzymatic activity, the function of BLNK is to temporally and spatially coordinate and regulate signalling effectors downstream of the B cell receptor. Function The function of BLNK was first illustrated in BLNK deficient DT40 cells, a chicken B-cell line, which exhibited an abrogated intracellular calcium mobilisation response and impaired activation of MAP kinases p38, JNK, and to a lesser degree ERK upon B-cell receptor (BCR) activation as compared to wild type DT40 cells. In knockout mice, BLNK deficiency results in a partial block in B-cell development, and in humans BLNK deficiency results in a much more profound block in B-cell dev ...

Epidermal Growth Factor Receptor
The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is a transmembrane protein that is a receptor for members of the epidermal growth factor family (EGF family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). In many cancer types, mutations affecting EGFR expression or activity could result in cancer. Epidermal growth factor and its receptor was discovered by Stanley Cohen of Vanderbilt University. Cohen shared the 1986 Nobel Prize in Medicine with Rita Levi-Montalcini for their discovery of growth factors. Deficient signaling of the EGFR and other receptor tyrosine kinases in humans is associated with diseases such as Alzheimer's, while over-expression is associated with the development of a wide variety of tumors. Interruption of EGFR signalling, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CBLB (genetics)
CBL-B is an E3 ubiquitin-protein ligase that in humans is encoded by the ''CBLB'' gene. ''CBLB'' is a member of the CBL gene family. Function CBL-B functions as a negative regulator of T-cell activation. CBL-B expression in T cells causes ligand-induced T cell receptor down-modulation, controlling the activation degree of T cells during antigen presentation. Clinical significance Mutation of the CBLB gene has been associated with autoimmune conditions such as type 1 diabetes.

Cbl Gene
''Cbl'' (named after Casitas B-lineage Lymphoma) is a mammalian gene encoding the protein CBL which is an E3 ubiquitin-protein ligase involved in cell signalling and protein ubiquitination. Mutations to this gene have been implicated in a number of human cancers, particularly acute myeloid leukaemia. Discovery In 1989 a virally encoded portion of the chromosomal mouse ''Cbl'' gene was the first member of the Cbl family to be discovered and was named ''v-Cbl'' to distinguish it from normal mouse ''c-Cbl''. The virus used in the experiment was a mouse-tropic strain of Murine leukemia virus isolated from the brain of a mouse captured at Lake Casitas, California known as ''Cas-Br-M'', and was found to have excised approximately a third of the original ''c-Cbl'' gene from a mouse into which it was injected. Sequencing revealed that the portion carried by the retrovirus encoded a ''tyrosine kinase binding domain'', and that this was the oncogenic form as retroviruses carrying full-l ...

SOS1
Son of sevenless homolog 1 is a protein that in humans is encoded by the ''SOS1'' gene. Function SOS1 is a guanine nucleotide exchange factor (GEF) which interacts with RAS proteins to phosphorylate GDP into GTP, or from an inactive state to an active state to signal cell proliferation. RAS genes (e.g., MIM 190020) encode membrane-bound guanine nucleotide-binding proteins that function in the transduction of signals that control cell growth and differentiation. Binding of GTP activates RAS proteins, and subsequent hydrolysis of the bound GTP to GDP and phosphate inactivates signaling by these proteins. GTP binding can be catalyzed by guanine nucleotide exchange factors for RAS, and GTP hydrolysis can be accelerated by GTPase-activating proteins (GAPs). The first exchange factor to be identified for RAS was the S. cerevisiae Cdc25 gene product. Genetic analysis indicated that CDC25 is essential for activation of RAS proteins. In ''Drosophila'', the protein encoded by the 'son of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CRK (gene)
Adapter molecule crk also known as proto-oncogene c-Crk is a protein that in humans is encoded by the ''CRK'' gene. The CRK protein participates in the Reelin signaling cascade downstream of DAB1. Function Adapter molecule crk is a member of an adapter protein family that binds to several tyrosine-phosphorylated proteins. This protein has several SH2 and SH3 domains (src-homology domains) and is involved in several signaling pathways, recruiting cytoplasmic proteins in the vicinity of tyrosine kinase through SH2-phosphotyrosine interaction. The N-terminal SH2 domain of this protein functions as a positive regulator of transformation whereas the C-terminal SH3 domain functions as a negative regulator of transformation. Two alternative transcripts encoding different isoforms with distinct biological activity have been described. Crk together with CrkL participates in the Reelin signaling cascade downstream of DAB1. v-Crk, a transforming oncoprotein from avian sarcoma viruse ...

Signal Transducing Adaptor Protein
Signal transducing adaptor proteins (STAPs) are proteins that are accessory to main proteins in a signal transduction pathway. Adaptor proteins contain a variety of protein-binding modules that link protein-binding partners together and facilitate the creation of larger signaling complexes. These proteins tend to lack any intrinsic enzymatic activity themselves, instead mediating specific protein–protein interactions that drive the formation of protein complexes. Examples of adaptor proteins include MYD88, Grb2 and SHC1. Signaling components Much of the specificity of signal transduction depends on the recruitment of several signalling components such as protein kinases and G-protein GTPases into short-lived active complexes in response to an activating signal such as a growth factor binding to its receptor. Domains Adaptor proteins usually contain several domains within their structure (e.g., Src homology 2 (SH2) and SH3 domains) that allow specific interactions with se ...

Gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as ...
